Abstract
Official abstract text for this publication.
A blow molding station may include a mold configured to support the preform. A blow molding station may include a stretch rod configured to stretch the preform within the mold. A blow molding station may include a nozzle configured to direct pressurized gas into the preform. A blow molding station may include a high-voltage module configured to impart an electrostatic charge to the pressurized gas directed into the preform.
First claim
Opening claim text (preview).
What is claimed is: 1 . A blow molding station for blow molding a preform into a bottle, the blow molding station comprising: a mold configured to support the preform; a stretch rod configured to stretch the preform within the mold and having a nozzle configured to direct pressurized gas into the preform; and a high-voltage module configured to impart an electrostatic charge via the nozzle to the pressurized gas directed into the preform. 2 . The blow molding station of claim 1 , wherein the stretch rod includes a rod section defining an interior passageway that fluidly couples the nozzle to a source of the pressurized gas. 3 . The blow molding station of claim 1 , wherein an insulator electrically isolates the nozzle from the stretch rod. 4 . The blow molding station of claim 1 , wherein the nozzle is positioned adjacent an opening of the preform. 5 . The blow molding station of claim 1 , wherein a high voltage conductor extends along the stretch rod and electrically connects the nozzle to the high-voltage module. 6 . The blow molding station of claim 1 , wherein the nozzle is one of a plurality of nozzles, and wherein each nozzle of the plurality of nozzles is electrically connected to the high-voltage module and configured to impart the electrostatic charge to the pressurized gas. 7 . The blow molding station of claim 1 , further comprising an actuator configured to move the stretch rod toward and away from the preform. 8 . A blow molding station for blow molding a preform into a bottle, the blow molding station comprising: a mold configured to support the preform; a stretch rod configured to stretch the preform within the mold and having a nozzle configured to direct pressurized gas into the preform; and a high-voltage module wherein the stretch rod and the nozzle are electrically connected to the high-voltage module. 9 . A blow molding station for blow molding a preform into a bottle, the blow molding station comprising: a mold configured to support the preform; a stretch rod configured to stretch the preform within the mold and having a nozzle configured to direct pressurized gas into the preform; and a high-voltage module wherein the nozzle is electrically connected to the high-voltage module and the stretch rod is electrically isolated from the high-voltage module.
